Construction of a gratitude questionnaire: The Gratitude Question-naire–20 Items (G-20).

Abstract

A new questionnaire was developed in order to have an instrument for the assessment of gratitude. An original pool of 50 items, constructed and reviewed using accurate standards, was filled out by 330 Spanish undergraduates (242 females, 72.5%; 88 males), aged 18-43, M = 23.33, SD = 4.87. An Exploratory Factor Analysis concluded with the selection of 20 items with an internal four-factors structure, resulting in a scale called Cuestionario de Gratitud–20 Items. A Confirmatory Factor Analysis using the matrix of policorics correlations showed an adequated fit of the model. The questionnaire and the four components showed an internal consistency between acceptable and high. The concurrent validity was checked by means of Pearson’s correlation with the Gratitude Questionnaire–Six Items Form, and discriminant validity was checked by means of confirmatory analysis of latent factors with the Purpose-In-Life Test. The results indicated that the dimensions of the Cuestionario de Gratitud–20 Ítems may be closely related with gratitude.
